Sign in using App Passwords

An App password is a 16-digit passcode that gives an app or device permission to access your Google Account. If you use 2-Step-Verification and are seeing a “password incorrect” error when trying to access your Google Account, an App password may solve the problem. Most of the time, you’ll only have to enter an App password once per app or device, so don’t worry about memorizing it.

Note: If you have iOS 8.3 on your iPhone or OSX 10.10.3 on your Mac, you will no longer have to use App passwords to use 2-Step Verification.

When you sign up for 2-Step Verification, we normally send you verification codes. However, these codes do not work with some apps and devices, like Gmail on your iPhone or iPad, Thunderbird, and Outlook. Instead, you’ll need to authorize the app or device the first time you use it to sign in to your Google Account by generating and entering an App password.
